List of Key=Value records to be set per target as target properties VS_GLOBAL_<variable> with variable=Key and value Value.
For example:
set(CMAKE_VS_GLOBALS
"DefaultLanguage=en-US"
"MinimumVisualStudioVersion=14.0"
)
will set properties VS_GLOBAL_DefaultLanguage to en-US and VS_GLOBAL_MinimumVisualStudioVersion to 14.0 for all targets (except for INTERFACE libraries).
This variable is meant to be set by a toolchain file.
